Figure 1 shows a side view or elevation of my improved apparatus. Fig. 2shows a, top

or plan view of the same. Fig. 3 shows the same view as Fig. 1, with thefront half of the revolving chamber removed to showthe The object'of myinvention is to arrange screw-blanks or other similar articles, and

convey them to a machine where some further operation is to be performedupon them, in a'more uniform and certain manner thanis generally done.

A is a revolving hollow drum'or chamber, of a cylindrical or oblatespheroidal form, one side of which has the circular opening a a a, forthe purpose hereinafter described. The other side has the axis attachedto its center, on which the drum turns.

y Around the circumference is a slot, '1) b b,

of sufficient width to allow the bodies of the blanks to pass through,but not the heads. This slot is, not continuous, but is broken at thepoints 0 c c, where the two halves of the drum are united. At thesepoints there are interior radial arms, dd d, attached to the inside ofthe drum, which have a slot in them, lengthwise, of the same width asthat in the circumferenceof the chamber above described. The junction ofthese radial arms with the drum is curved,'so that blanks, resting inthe circumferential slot by their heads, can pass around the curve, andout upon the radial arm.

'- B is a shield attached to astandard, C,

passing through the openingaa a, and is stationary, and does not movewith the revolving chamber A. This shield has a curved surface, 0 0,along which" the ends of the radial arms pass close without touchingit..-" The Witnesses:

etandard 0 also supports the inclined conforms part of the shield B.These ways curve round, and lead through the opening a a a' to any pointwhere it is desired to deliver the blanks to a machine.

E is a plate attached to the conductingways, for the purpose of ,catching and returning to the drum any blanks whichfall from above as thedrumrevolves.

The operation of my invention is as follows: The blanks are placed inthe drum or chamber A, which is slowly revolved with either a continuousor an intermittent motion, communicated by a belt or ratchet, or anyother convenient means. As the drum revolves, the arms (l pass through.the blanks, which fall over and over to the bottom of the chamber. Suchof the blanks as fall into the slot b at the bottom, and such as arecaught by .the arm d asitpasses through, are forced out upon the arm,resting by their heads in the slot as the arms rises, and fall againstthe] shield B, which retains them in the arm untilit rises suflicientlyhigh to have its slot correspond with that of the conveyingtrough B,when the blanks pass into it, and are carried forward down the incline.As each successive arm d passes through the blanks in the bottom of thedrum it brings up blanks,

as above described, and delivers them into the conveying-trough.

The'curved surface 0 e of the shield-extends down sufliciently far toprevent any blanks which may be taken up by the arms d from being caughtdrum revolves.

The interior of the drum may be of any form that will conduct the blanksinto the slot b.

Claims.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The arrangement of the revolving drum 7 A, with its slot b, arms d,and the shield B,- substantially as described.

2. The revolving drum A, with its slot b,

arms 11, and shield B, in combination with the conducting ways D,substantially as described. I
